manipulation. The object of my. improvements to proltd vide mechanism of the class specified simple in construction and efiicient in operation.

To these ends my improvements comprise means illustrated in their preferred form in the accompanying drawings wherein:

Figure 1 is a side elevation looking from the left of Fig. 2, with the left hand side frame and the cams fixedthereto removed. Fig. 2 is a sectional elevation, to an enlarged scale, on line 2, 2 of Fig. 1, looking in the direction of arrow A. Fig. 3 is a plan view of a portion of what is shownin Fig. 1. Fig. 4t is a plan view',.similar to a portion of that of Fig. 3 but with the parts in different positions. Fig. 5 is a plan development of one of the cams-and Fig. 6 is a side elevation showing arrangement of cams. All the figures except Fig. 2 are to one scale.

tion wherein two opposite edges of the presently to be folded envelop are parallel with such web edges or wherein the major axis of the blank is normal to its direction of travel.

My improved mechanism may be supported in the usual side frames 3, 4. Rotary cutter 5 is provided with cutting edges as 6, 7, 8 whereby preferably at each rotation two envelop blanks as 10, 11 are severed successively from the leading end of web 9, by the coaction of said cutter 5 with rotary anvil 12. Said blanks during their severance from the web and thereafter are advanced synchronously withthe surface speed ofsaid cutter by means of upper and lower edge rolls as 13, 14 and 15, 16 respectively. Said pairs of upper and lower-rolls may be geared together by gears, as 17, 18 to rolls 15, 16 respectively. The usual table as 19 may be"provided, over which to advance ll desire to haveit understood that the invention is not limited to the particular construction and arrangement of parts which it have illustrated and shall hereinafter describe, and that various changes may be made in the mechanism shown Without departing from the spirit or scope of the mvention, and that the phraseology which I em loy is for the purpose of description and not of limitation.

.My improvements are particularly adapted for usein connection Withmachines for making envelope from diamond shaped bin cut diagonally: from a continuous web. One of the major problemsinsuch a ma chimeis the turningofthe blank from its primary relation to the web in which tweet; im- 'oppnniteaen'deeare in line wide thescdgenofi I nichrespecti'vely to an are ne 1 y y ry tn a p'e said blanks to turning cylinder 20. Said cylinder or rotary frame is preferably adapted to carry a plurality of blank turnmg devices, one of which is indicated in a general way by T. Said frame is fixed to shaft 24 which may be the main shaft of the machine. Said. devices '1 are spaced equally about. the periphery of said frame and said frame is rotated in clockwise direct1on, Fig. 1, at a peripheral speed equal to the speed of advancement of web 9.

Receiving cylinder 22 is rotatably mounted adjacent to frame 20 and their axes are parallel. Said receiving cylinder 22 is provided with the usual grippers as 23 actuated by fixed cam 57 for gripping to its periphcry ablank delivered in turned position thereto by the devices '1. respectively of frame 20. Said cylinder 22 may be provided if desired with known folding means not shown for the envelop.

Cutter 5, anvil 12, edge feed rolls 218-13, 14, 15, 16, frame 20 and cylinder 22, are all geared together by suitable spur gears on their respective axes,those gears being omit ted from the drawings as unnecessary to "illustrate this invention and as well understood in the art of such construction.

irecting' attention now to the detail construction of my improved turning devices,

otwill suffice for all. Rotatably mounted frame 2(iinetem'26 of turning head 27. The

orfimid. 1, vi a. prefer i l i parallel. n no a line radial to axis 24 of frame 20. R0- tatably mounted in bearings 31, in said head and normal to stem 26, is clip shaft 28 and fixed to one 'end ofsaid shaft is clip 29 for coaction with foot 30 outstanding from head 27, said clip and foot forming a gripper for engaging at one point, the envelop blanks to be'turned. Fixed to sleeve 33 rotatably mounted on shaft 28 is clip 34 for coaction with foot 35 outstanding from head 27, said clip and" foot forming another gripper for engaging said envelop blank at another point. .Fixed to that end of shaft 28 opposite clip 29 is arm 36 carrying roll 37 for engagement with cam 38 for actuating said clip 29. Spring 39 has one end thereof fixed tobearing 32 and the othe'r end fixed to collar 40 secured to shaft 28, for causing roll 37 toengage its cam and for causing clip 29 to Tcoact with foot 30. Fixed to .the outer-end of sleeve 33 is arm 41 caract with foot 35'...

rying roll 42 for engagement with cam 43 for actuating aclip'l34. Spring 44 has one end thereof fixed to hearing 31 and the other end fixedto: collar .45 secured to-the inner .end of sleeve-33hr causing roll 42 to engage its cam and for causing clip 34 to co- .It will be observed, when an envelop blank as 10, Fig. 3, is advanced from the cutting device-to be engaged and gripped by one of the turning devices T, that clip 34 must first come into'action to grip the blank and that foot '35 thereunder should preferably lie coinid'ent with the periphery of cylinder orframe 20 to be in suitable receivingposition for the blank. It will also appear that after said clip has gripped the blank to foot 35, the turning device must be moved radially outwardly coincident with and proportionate to the advance movement in clockwise direction, Fig. 1, of frame 20 so as to present foot 30 in.=coincidence with the periphery of said frame at the time 'of' the coaction of clip 29 therewith for grip;- ping one of the sides ofv the blank which is parallel with the path of'the blank. For causing saidturning device to move thus outwardly I mount in the lower or inner end ofstem 26, roll 46 for engagement with cam 47 fixed to the inner end of sleeve'48 bolted to'sideframe' 3 concentric .with shaft 24, Figs. 1 and'2; aid stem 26 is urged to its 'inner'positionand roll 46 is held to engagement with cam 47 by spring'49 interposed between theinn'er face of bearing 25 and collar 50 fixed therebelow: tostem 26. In Figs. 1 and 3 device T is shown inits raised or outer position, in Fig. 1 clip 34 having previously operated to grip the blank at one pointandwlip29 having just descended to grip said blankfatisin other; point. Device '1 now has sai'd jblan lifull control and as'soon as that bla distance farther from'the's bite of edge feed advanced a short rolls as 15, 16 said device T turns in clockwise direction, from the position of Fig. 3 to the position of Fig. 4 and position C, Fig. 1, whereby the blank is located with its major axis in parallelism with the axis of shaft 24 of frame 20. However the two points of gripping of said blank by device T are now, radially of frame 20, beyond the periphery of said frame, see position C, Fig. 1. Therefore cam 47 falls away directly after the point of contact of roll 46 therewith, position whereby said device T in the clockwise movement of frame 20, is presently lowered to cause the points of gripping-of the blank to coincide with the periphery of said-frame, for delivery to receiving cylinder 22.

For causing device T to turn axially with stem 26, as above described, I..provide arm 51 outstanding from collar 50 on said stem. On the outer end of said arm 51 I provide roll 52 for engagement with cam 53 fixed to device are returned to their initial positions readv to engage another blank.
